Abstract

Procédé pour décaféiner du café On soumet l'extrait aqueux de café à une extraction par du CO2 , par exemple dans une colonne 3 à corps de remplissage fonctionnant à contre-courant, dans des conditions super-critiques, de préférence 32 à 140 degrés C et 75 à 350 bars. La phase formée de CO2 et de caféine est lavée à l'eau, dans les mêmes conditions de température et pression, dans une tour 5, puis on sépare le CO2 par détente 6 et la caféine par distillation 7 de la solution de caféine formée. Application à l'obtention de cafés en solution ou solubles dont on a enlevé jusqu'à plus de 98 % de la caféine.
